In the actual electronic radiator design, weight and volume allow, increasing the width of Chicco's electronic radiator can also be an effective method to reduce thermal resistance. The geometric factors of Chicco's radiator affect the geometric factors, including the relationship between thickness, height, rib spacing, and junction temperature. With the increase of the fin thickness, there is no obvious change in the thermal resistance and junction temperature of the electronic radiator. The small change first rises and then drops, and the temperature gradient changes from negative to positive.

    In fact, changing the thickness of an electronic heat sink can only change the internal heat transfer performance and the internal temperature field. It cannot change the area of the ribs contacting the outside air, and cannot improve the convective heat transfer coefficient. Therefore, the thickness change has little effect on the thermal resistance of the electronic heat sink. In the actual design of the electronic radiator of Chicco, the parameters of the fin thickness are not very important. If the rib is too thick, in addition to increasing the weight of the electronic radiator, the width and the number of fins will also reduce the rib spacing.
